This 304 stainless midpipe is the easy solution for a complete bolt-in 3" exhaust for our customers with K24A2 swaps in their NA and NB Miatas.

This midpipe bridges the gap between our 4-2-1 Race Header and our 3" Race Exhaust System, and it also adds the necessary flex coupling along the way. 

Just use the V-band clamp included with your header, as well as the hardware and gasket included with your exhaust system and you're good to go.
